Despite the fact that it's extremely "awkward" that The Bachelorette star Ashley Hebert dated both her fiancé J.P. Rosenbaum and The Bachelor's Ben Flajnik at the same time, she says that Ben will definitely be invited to her wedding.

OK! met up with Ashley and J.P. at the Origins Rock Earth Month Concert at Webster Hall in NYC on April 18, and they filled us in on all their wedding plans, including who's on their guest list!

And there's no doubt in our minds that Ben's fiancée Courtney Robertson will be invited to the nuptial, too. Ashley raved about the model, saying that she's a lovely girl in person.

"She was great!" Ashley told us. "That’s the thing about people on the show that get a bad rap, you meet them in real life and you’re like 'Oh, they’re cool!' And I knew it was going to be that way with Courtney. It is what it is. I’m sure she’s fine with everybody now."

As for whether or not Ashley and J.P., who have "no plans" to get married any time soon, think Ben and Courtney will make it in the long run, the lovebirds have faith.

"I think they’re doing a great job," J.P. explained. "They’ve been completely off the grid and I’m sure they’re just focusing on each other and their future together."

"They both are very level-headed, realistic people and I think they’re just doing it on their own," Ashley added, saying that the "down-to-earth" couples like Trista and Ryan Sutter are the ones that sat together in the end. "I don’t think they need advice from us."
